This utility model belongs to the field of edge-wrapping equipment and provides a fully automatic edge-wrapping device, including: a frame equipped with a support platform for placing the packaging film to be wrapped; a heating mechanism mounted on the frame, which can be moved closer to or further away from the support platform to ensure the heated packaging film adheres tightly to the product; a pressing mechanism and several auxiliary mechanisms, with the pressing mechanism movably positioned above the support platform. Compared with the prior art, the advantages of this utility model are that by heating the packaging film to adhere more tightly to the product surface, and with the pressing mechanism pressing the product onto the packaging film, while the peripherally distributed auxiliary blocks push the edge of the packaging film towards the side wall of the product, a uniform and wrinkle-free edge-wrapping effect is achieved. The entire edge-wrapping process requires no manual intervention, improving production efficiency, reducing labor costs, and ensuring the consistency and aesthetics of the packaging film when wrapped on the product, making it suitable for continuous industrial production.
